Review on Reversible Pink Camo Kids Placemat/Chalkboard - AM PM Products by Kelsey Brown

I love the design, super cute. problem with cleaning. I wish I could throw this in the washing machine but I can't because of the plaque on the back. I bought this for my kids to use as a preschool lunch napkin and it's starting to look a little rough (about 2 1/2 months of use, twice a week). I don't really understand how it got so dirty judging by the food I put in her lunch box. I wipe it down every day when it comes home, but there are stains on it that cannot be washed off. It looks like brown water got in and soiled it. I never used his chalky side,
